[XRP Ledger Proposes Quantum-Resistant Account Design, No Additional Fees Required for Users] According to CoinDesk, the XRP Ledger Foundation proposed a quantum-resistant account design in its 2027 protocol roadmap updated on November 4th. This design allows account owners to add quantum-resistant signature keys to their accounts and disable the original keys to prevent future quantum computer attacks. Since each account-signed transaction exposes the public key on-chain, any account that has ever sent payments, including all exchange wallets, has already exposed that public key. The new key will use the ML-DSA-44 signature scheme approved by the National Institute of Standards and Technology (NIST) in 2024. This key is relatively large, with the key and signature totaling 3732 bytes, increasing the size by approximately 3.6KB with each protected transaction. However, users will not need to pay any additional fees; the base fee remains unchanged, and the additional storage costs are borne by the network operator.
